Title: Printing head
Inventor: TETSUMOTO JIYUNJI
IPC: B41J2/265
Filed: 1983-01-19
Abstract: PURPOSE:To make it possible to prolong the life of a printing head, in a wire matrix type printing head, by providing a wire guide at a position where each wire is moved in a predetermined amount in the direction opposed to the repulsive force due to the curvature of said wire. CONSTITUTION:Because the wire 1 of a matrix type printing head is curved in a radius of curvature R, such repulsive force that the wire 1 is returned to the original state is always acted in a b-direction. Therefore, each guide orifice 13 of a guide 12 is provided so as to be shifted only over a predetermined amount delta' so that the center position of the leading end dot 14 of the wire 1 is shifted to the direction opposite to the b-direction only in a predetermined amount delta from the center 15 of a normal dot pattern. By this mechanism, at the beginning of the production of the printing head, printing such that the dot pattern to be printed is alternately shifted only over delta but a normal pattern is obtained corresponding to the abrasion of the guide orifice 13 and, if abrasion further advances, printing shifted to the reverse direction is performed. By this method, the shift due to abrasion is distributed to both sides and the life of the printing head can be extended.

Abstract: PURPOSE:To provide such a device that is installed in an intake passage sepa rately from a throttle valve and having no movable part operating a valve element to close this intake passage at time of something wrong and less in power consumption. CONSTITUTION:A valve stem 3 of a valve element 5 is installed eccentrically more upward than an center line X-X of an intake passage, and a part 5a at the more up-stream side than the vale stem 3 of the valve element 5 is formed into a larger area than that of a part 5b at the downstream side, then a magnet 8 is attached to the part 5a. An iron core 11 and a magnet coil 12 magnetizing this iron core both are installed in the upper part of an intake cylinder. The magnet 8 attracts the iron core 11, keeping the valve element 5 in a full-open position. An electric current flows into the exciting coil 12, magnetizing the iron core 11 temporarily and repulsing the magnet 8 with magnetic force, thus the intake passage is closed.
